Motivation

Schema synchronization defines the design of the schema synchronization framework.

This document defines how DDL operations interact with DML operations (namely, how DML operations after the DDL are handled in transactions started before the DDL).

The document also describes how we deal with basic schema changes (these are changes that have nothing to do with indices and don’t require existing data validation) under the Schema Synchronization framework. Compatibility issues are covered for basic schema changes.
